HYDRAULIC GIANT.

Specification of Letters Patent.

Application filed January 24, 1910.

' To all whom it may concern:

Be it known that I, SENECA L. BERRY, citizen of the United States,residing at Sunnyvale, in the county of Santa Clara and State ofCalifornia, have invented new and useful Improvements in HydraulicGiants, of which the following is a specification.

This invention relates to hydraulic giants. Its object is to so designand construct water nozzles of this class that a much more effectheconstruction and combinations of parts in section.

as hereinafter more fully described and claimed, having reference to theaccompanying drawings, in which Figure 1 is a side elevation of themonitor. Fig. 2 is a plan view of the ball-joint partly in section. Fig.3 is a side elevation Fig. 4 is a cross section of the nozzle.

2 is a stationary elbow section; 3 is a complementary elbow, .turnablehorizontally about avertical pivot or king bolt 4, and having a ball andsocket connection with the nozzle 5, which latter turns in a verticalplane about horizontal pivots 6. The base of the section or elbow 3 hasan outwardly projecting flange-7, against which a packing ring 8 is heldby a clamp ring 9 adapted to rest upon a complementary annulus orshoulder 10 formed upon the horizontal edge of the stationary elbow 2.Preferably the lnner surface of the flange 7 is turned off so as to forma recess 11, and the ring 8 being of sufficient width to cover the ridge12 of the section 2 when the giant is in use, water pressure will forcethe gasket down tightly upon the ridge 12, thus effectively preventingleakage at this joint.

In order to facilitate horizontal turning about the king bolt 4,suitable anti-friction frustro-conoidal rollers 13, Fig. 3, are intro-.duced between rings 14 and 15 surrounding the bolt 4 and just beneathnut 16. Thus the thrust of water pressure in the elbow 3 is borne by theconical rollers 13 and the nozzle may be easily turned from side toside.

Serial No. 539,808.

An important feature of myv invention resides in the particular meansand method of connecting the nozzle 5 to the elbow 3 so as to greatlyreduce the tendency of the water entering the nozzle to form eddies,which latter greatly lessen the speed of discharge as well as cause thewater to swirl and separate as it leaves the nozzle.

It is essential in hydraulic giants to provide means whereby the nozzlemay be moved in a vertical plane in conjunction with the horizontalswing, and this is commonly accomplished by securing the nozzle to theelbow by a ball and socket joint in which the socket is formed on thenozzle and the complementary ball is made on the elbow, which thusproduces an enlarged chamber at the inner end of the nozzle into whichthe water is discharged from the comparatively smaller passage in theglobular elbow. By this old construction the water forms numerous eddiesand counter-currents which check the flow and cause it to swirl andseparate immediately upon leaving the nozzle. It is to improve .on thisvery defective form of joint or connection and to prevent the formationof eddies and obtain a more compact jet of water, that I have clesignedand employ a ball-shaped joint section 17 removably attached or in anysuit able manner united to the nozzle 5 and fitting a correspondingball-seat 18 on elbow 3. That is to say, in my construction my nozzlefits into the elbow, while in the old style giant the elbow fitted intothe nozzle. The nozzle is movable upon the pivot pins 6, which screwinto lugs on a metal ring 19 bolted to a flange 20 on the socket-elbow 3and clamping thereon a packing-ring 21, Fig. 2. The bore of the nozzle 5is practically of the same diameter throughout its entire length, andtherefore the water is permitted to flow evenly, smoothly and uncheckedthrough the joint from the elbow 3, and no detrimental currents are set11) in the nozzle to reduce the effectiveness 0 the jet issuing from thenozzle, which may be tapered if desired. To assist in overcoming thethrust due to the use of water under high pressure, appropriate meansare employed to partly relieve the pins 6; straps 22 being securedrigidly to a flange 24 on the nozzle and pivoting about the pins 6, andU-bolts 25, secured in the elbow flange 20, are passed through ring 19and around the lugs in ring 19 into which the pivots 6 screw.

The several oints of the sections are suitably packed by the gaskets 8and 21; and a particularly efficient means of packing against leakage atthe king-bolt in the elbow 3 comprises an inverted flexible ring 25,Fig. 3, of suitable packing material of inverted U-shape, the outer sideof which seats in an annular recess 26, and the inner side bears uponthe bolt 4. Consequently, water under pressure may reach the under sideof the ring 25 and expand the ring sufficiently to snugly seat upon thesupporting surfaces and so prevent leakage at this juncture; and tofurther insure against leakage here a gasket 27 is interposed betweenthe roller bearing-ring 15 and the top of the elbow 3.

In connection with the interior ball and socket arrangement of thenozzle, I so construct the nozzle that no rivets are presented on theinterior, and there are no lap seams exposed; this smoothness andfreedom of projections being accomplished by forming the nozzle 5 of aplurality of longitudinal cylindrical or tapering segments 28 of curvedcrosssection and having radial flanges 29 projecting exteriorly andriveted together, reinforcing strips 30 being adopt ed when desired.

As a further means of preventing swirling and eddying of water in thenozzle 5, I insert the longitudinal strips or vanes 31 between theadjacent flanges 29; these vanes extending parallel to the flow of waterand projecting radially into the nozzle bore so that they acteffectually to prevent the formation of counter-currents and also serveto stiffen the nozzles.

One very important point of this invention is the arrangement of theball socket in a double jointed giant. It has been customary to put theball on the upper casting. This passes the swiftly moving water from asmaller to a larger section suddenly, resulting in eddies and streamdisturbance which seriously affect the jet issuing from the nozzle. Inthe arrangement shown it is easy to arrange a good waterway and to makewhatever section changes that are necessary from the larger to thesmaller, which is attended with less loss and disturbance to the stream.The second point is the spout construction shown. The object is toobtain smooth surfaces inside, free from rivets and with straight, truevanes, the latter being required to prevent any tendency to swirl whichmay arise when the water makes the turns through the elbows. These vanesare usually made of angle iron and riveted inside of the spout, and thespout is usually of the same construction as riveted steel pipe and moreor less rough. Beyond these two main features are the features of theball section 17 fulcrum pin, its U-bolts 25, the supporting straps 22,and the roller bearings on the king-bolt.

Having thus described my invention, what I claim-and desire to secure byLetters-Patent, is:

1. In a hydraulic giant, the combination of an elbow section having asocket, a nozzle with a ball to fit the socket, the socket having anoutside annular flange, a ring bolted to the flange with a packingsecured therebetween, which packing bears on the periphery of the ball,the ball having recesses and pivot pins fitting said recesses andscrewing into said ring which is secured to the flange, and U-boltspassed through'the ring vand flange and embracing said pivot pins.

2. In a hydraulic giant, the combination of an elbow section having asocket, anozzle witha ball to fit the socket,the socket having anoutside annular flange, a ring therebetween, which packing bears on theperiphery of the ball, the ball having recesses and pivot pins fittingsaid recesses and screwing into said ring which is secured to theflange, U-bolts passed through the ring and flange and embracing saidpivot pins, and straps on the outer ends-of said 3. In a hydraulic giantand in combination with the elbow section thereof, a-nozzle made up of aplurality of longitudinal cyradial vanes within the nozzle.

In-testimony whereof I have hereunto set my hand in the presence of twosubscribing 'wltnesses.
